28/40-Pin 8-Bit CMOS FLASH Microcontrollers

PIC16F874 There are four devices PIC16F873PIC16F874PIC16F876 and PIC16F877 covered by this data
sheet. The PIC16F876PIC16F873 devices come in 28-pin
packages and the PIC16F877PIC16F874 devices come in
40-pin packages. The Parallel Slave Port is not
implemented on the 28-pin devices. By Microchip Technology Inc.
